vTo all whom it may concern:

Be it known that l, ANDREAS P. LUNDIN, a citizen of the United States, and a resident of ldayside, borough of Queens, county of Queens, and State of New York, have invented certain new and useful Improvements in Life-Boats, of Which the following is a specification.

This invention relates to improvements in liteboats,

By the use of my invention 1 am enabled to produce a life boat, which, in addition to itsconstructional charaeteristics of great strength, durability and :substantial indestructibility, will have ashell or hull provided with a well havingseating devices for passengers, which hull, Without useo'l ballast, heavy heels, center boards or=other similar dev1ces, will be substantially 'noncapsizable and extremely stable and will have a passenger protective metalhc housing oi? a perculiar non-water resisting and highly unstable conformation erected above the hull inclosingthe well and provided withwater-tight closures so as to form with said well abuoyant water tight compartinent, whereby in case theboatis capsized otherwise, it will quickly right itself and regain its normal position, the selt-rightingoif the boat being further insured because the hullgon account of its conformation and its seating devices, has a great preponderance over the housing of properly distributed weightand also has buoyant air chambers and conibination fenders and buoyant sides, which not only add weight but by reason of their buoyancy assist in theseltrighting oi the boat.

Furthermore such ahousing will provide itor the passengers adequate shelter, proteetion, air, light, observation and rowing tacilities and ready ingress and egress, and

when in normal position its'peculiar novel contour willtend to'break and lessen the shock otcontacting waves.

Another novel feature of my inventionis the provisionin a passenger protectinghousing otside ports or window apertures for the admissionot light and'thetransterence ot'passengers in case otlnecessity, having row-lock notches formed 1n the lower edges Ethernet", twater tight 'elosures liter the ports and independent water-tight closures for the row-lock uiotolies hinged to the {1 30I l31 closures.

ltn-the preferred term-of my invention the hull v-has wide substantially tlat bottom with flat sides, theeontourvof the latter beling roundedout byveombined supplementary sides and tenders of balsa wood, has a double bottom with intermediate ,air it chambers and has rounded or curved front 1 and stern portions, the peculiar conformation lot the hull vbeing exceedingly stable without the use of heavy heels, centerboards'or the like, which notonly take up valuable space which may be otherwise usefully occupied,ibut prevents the ready handling of the boat on ship board, said con-formation also 1p ermitting theboatto be superimposed or nested ZLlJOVGbZMbOtllJyOf tl'ieltype which has a similar shaped hull :and collapsible superstructures or vveather-boards,1 such a as described in my former application fiierial NofiQdAi-BQ, andinay bereadily handledby the forms of davits a and other boat handling devicesiat present in use; entrance decks fore and aft substan ti ally i level. with the; sides of the hull a well provided with side benches and thwarts extending from i the fore to l the aft deck and a passenger protective housing erected above raid well having water-tight closures and pretlerably beingof the rigid construction illustrated, which consists of a series of metallic plates abutting each other, each platehaving an integral marginal semicircular groove contiguous to itsabutting edge, the abutting platelapping said groove and riveted thereto on opposite sides of the groove, the housing being reinforced and supported by transverse ribs comprising metal stripsor bars havinga ll shaped central portion and laterally projecting flanges to permit riveting to the shell platin In the accompanying drawings, in which similar reference characters designate corresponding parts throughout the several views,

Figure ml is v a plan view of any improved self-righting boat oft,th li' aaftthalf eta .saiduhoat;

Fig. 4 is a detailed sectional view of the ventilating tubes preferably employed b me; V

Fig. 5 is a detail of my preferred construction of window closure;

. Fig. 6 is a transverse sectional view of a modified form of boat embodying my invention; and

v Fig. 7 is a View in plan of another slightly modified form.

Referring now to these drawings 1 indicates a hull or shell of metal or other suitable material having a substantially flat bottom 2 and provided with a well or passenger seating compartment 3, a double bottom or floor 4, the space between the bottom 2 and floor 4 of the Well being divided into a series of air-tight compartments or chainbers 5 by suitable dividing partitions 6, and fiat sides 7 terminating in rounded'bow and stern portions 8 and 9 respectively, having exposed decks'8 9 substantially level with the sides of the hull. 7

As illustrated in Figs. 1, 2 and 3, the well or passenger seating compartment 3 is oblong or box shaped in configuration and is provided at its extreme upper edges with marginal seats 10 and thwarts or cross seats ll'which assist in reinforcing the shell to form a structure of great strength and rigidity. A series of suitable bailing tubes 12 preferably connect openings in the fioor of the well and the bottom of the boat, which the hull.

and preferably it water-tight.

tubes may be provided with any suitable valve mechanism to permit water to be discharged but to prevent water to enter said well.

The flat metallic sides are preferably rounded out by what I shall term supplementary sides 7 of highly buoyant material of balsa wood which has been treated so asto close its pores and make These supplementary sides are preferablydetachably secured to the hull by means of straps 7 extend both above and below the'water-linaand the top edge of the same being squared and covered with a side strip 7 so as to form a narrow deck extfinding laterally at opposite sides of the we I The thwarts and side seats are also preferably braced by means of struts13-13 at opposite sides which are connected by diagonally extending connecting rods 14 having turn-buckles 15-15 and also by a centrally located strut 16, thus preventing the sagging'of the seats and further reinforcing 'the hull and has a rounded or semi-spherical conformation so that, if the boat capsizes, the surface presented to the water will be as unstable and non-water-resbting as possible. Said housing is preferably provided with entrance or exit ports 1818 at the front and rear opening in the decks 89 and said ports are provided with watertight closures 1919 having suitable handles or knobs 20 with means for compressing a watertight packing 21 inclosed in a marginal groove in the closure and surrounding the port. Said housing is, as illustrated, provided with a series of glazed side ports 22, each having a glazed watertight closure 23. As illustrated, said ports are elliptical in shape and provided with two circular window lights 24521, the closure being hinged to the upper edge of the port and provided at its lower edge with thumb screws 25-25, or other appliances for applying pressure on a watertight packing surrounding said port.

The lower edges of each of said ports are preferably provided with a row-lock notch 26, which notch is provided with a watertight closure 27 hinged on the closure of the port 25, said row-lock closure 27 being also provided with a thumb screw or other pressure applying device 28.

also preferably provide in the ceiling of said housing a series of ventilating tubes 29 adapted normally to remain in open position for the admission of air to said housing but to close automatically if the boat is capsized to prevent ingress of water therethrough. As shown, each tube 29 is provided with a valve 30 pivoted eccentrically as at 31, the short side of such valve being provided with a weight 32 adapted normally to retain the same in open position, a stop pin 33 being also preferably provided to prevent abnormal swinging of the valve. Obviously, when such ventilating tube is inverted the valve 30, owing to the position of the weight 32 will automatically close upon its seat 34. Said ventilating tubes are also preferably provided with a rain shedding cover 35.

In my preferred form of construction the housing 17 will be composed of a series of metallic overlapping plates, the adjacent edge of the outermost plate being provided with a marginal semi-circular shaped groove 17 and being riveted to the inner overlapping plate on opposite sides of said groove by means of rivets 171'4- and the housing is also preferably reinforced by means of transverse ribs, each rib comprising, as shown in Fig. 3, a strip or bar of sheet metal having a U-shaped center portion 17 and laterally extending flanges 17 on opposite sides thereof, which flanges are riveted to the outer plating.

The construction above described constitutes a very rigid and light construction and is suitable for use in any part of a metallic life boat though especially suitable for a housing such as herein described.

In Fig. 6 I have shown a slightly modified te races ing, instead of having a single flat inclined face, as illustrated in Fig. 1, has tWo flat inv clined faces 3838 terminating in a central line 39.

I also preferably provide observation ports (not shown) at front and rear sides of the housing, Which ports Will be provided with stationary Watertight closures.

Having described my invention, I claim:

1. A life boat embodying a hull having a Well and a housing erected above said Well, entrance and exit ports provided With Watertight closures, side ports having row-lock notches formed in their lower edges and a glazed Watertight closure for each of such side ports and notches.

2. A life boat embodying a hull having a Well and a housing erected above said Well,

entrance and exit ports provided with Watertight closures, side ports having row-lock notches formed in their lower edges, a glazed Watertight closure for each of such side ports and an independent Watertight closure for the row-lock notches hinged to the side port closures.

3. A lifeboat embodying a buoyant hull having a seating compartment of substantially oblong, box-shape conformation and provided With a substantially flat bottom and substantially flat sides, buoyant fenders at the opposite sides of said seating compartment substantially coextensive in length With the said sides and also extending both above and below the Water-line and a pas senger-proteotive housing inclosing said seating compartment and having side Walls extending upwardly in a curve inclining inwardly from the sides of said hull.

In Witness whereof, I have signed my name to the foregoing specification in the presence of tWo subscribing WltIlESSBS;

ANDREAS P. LUNDIN.
